A dimensional analysis is performed on the drag on a boat. When the effects of viscosity can be neglected, the Euler number based on the drag $D$ experienced by the boat is a function of a Froude number. The effects of the dimensions of the boat can be represented by its length $l.$ The drag on a model of the model is measured as $0\mathrm{.}35N.$ If the ratio of $\frac{?}{?}$ for a full$-$scale model to the value of $\frac{?}{?}$ for the model is $51,$ calculate the expected drag on the full$-$scale boat. Your answer should be to the nearest $kN.$

The properties of the water in the model test matches those for the full$-$scale boat.
